Iraq was invaded for Oil, as well as to fuel the war economy for the military and private sector (in my opinion).
I too used to eat up the spoon fed information from corporate media until around 2002 when I began to get my info from PBS,NPR and the BBC World Service. I enjoy Google News as well as you get articles from around the world regarding a particular subject for fact checking. Once you have a more worldly view, you tend to see things a different light all together.
Side note: I see Fox News as nothing more than a mouthpiece for the whitehouse AKA a fear mongerer.
In 2003, University of Maryland researchers studied the public’s belief in three false claims — that Iraq possessed WMD, that Iraq was involved in 9/11, and that there was international support for the U.S.-led invasion of Iraq. The study found "those who receive most of their news from Fox News are more likely than average to have misperceptions. Those who receive most of their news from NPR or PBS are less likely to have misperceptions. These variations cannot simply be explained as a result of differences in the demographic characteristics of each audience, because these variations can also be found when comparing the demographic subgroups of each audience."
